Terrible.
The thing about the stuff from the originals is that they made you go, "whoa! What is THAT?!" All of this stuff makes you go, "eww, what IS that?" What really bums me out about the whole thing is that they had the opportunity to show us something new and awesome. They could have shown us what the world is like now that Ghostbusters have been around for 30 years. Do we still need them, or have ghosts been pretty much eradicated? Do they have them in every city now like we do firefighters. How much has the technology they used advanced? Have ghosts wizened up and become more difficult to catch? Instead, they are giving us a total (unnecessary) reboot and showing us the exact same stuff we already know but with a crappy cast.
And I have no problem with an all female Ghostbusters troop. If they wanted to do a movie where for instance Ray is the only one left, he decides to retire and leave the company to his daughter, and she hires a couple of her friends who she works with at her college, I could get behind it as long as the women the cast were actually good actresses and the writer/director was somebody better than Paul Feig. There are tons of women who I find infinitely funnier than the people in this movie.
